ALGO.html() doesn't return element - confusing API

[williamsharkey]

Problem

ALGO.html is a tagged template function but it sets document.body.innerHTML instead of returning an element:

// Expected:
const el = ALGO.html\`<div>hello</div>\`;
el.textContent; // "hello"

// Actual:
ALGO.html\`<div>hello</div>\`;  // returns undefined, sets body

Impact

• Confusing for developers expecting jQuery-like behavior
• The Code Metrics app failed silently because:

  const canvas = ALGO.html\`<canvas></canvas>\`;  // undefined!
  canvas.getContext("2d");  // Error: cannot read 'getContext' of undefined

Options

1. Document clearly - Add JSDoc/comments explaining it sets body
2. Rename - Call it ALGO.setBody() or ALGO.render()
3. Change behavior - Make it return the created element(s)
4. Add alternative - Keep current + add ALGO.create() that returns element

Workaround

Use standard DOM:

const canvas = document.createElement('canvas');
canvas.width = 400;
